I wish to install a customised version of input mono fonts on macOS.
First, I tried
home.file."Library/Fonts/HomeManagerExtra".source = ../custom-fonts;
which successfully symlinked the custom fonts into the macOS fonts directory. But Font Book did not pick up the symlinked fonts. It did pick up the fonts specified in home.packages.
I observed that home-manager itself had copied, not symlinked, the fonts I had specified in home.packages. So I set out to instruct the home-manager to copy the custom-fonts through an activation script:
home.activation = if pkgs.stdenv.isDarwin then
{
copyExtraFonts = lib.hm.dag.entryAfter ["writeBoundary"] ''
$DRY_RUN_CMD rm -rf $VERBOSE_ARG ~/Library/Fonts/HomeManagerExtra
$DRY_RUN_CMD cp -r $VERBOSE_ARG ${../configs/fonts} ~/Library/Fonts/HomeManagerExtra
'';
} else { };
Note that I have set the script to be entered after writeBoundary, as specified in the home-manager manual.
The custom-fonts were copied successfully when the ~/Library/Fonts/HomeManagerExtra directory did not exist. However it failed on a second run with a permission error:
>> home-manager switch
/nix/store/1pjsk5hmq9daj80avfna3njzqdx3rxq9-home-manager-generation

There are 113 unread and relevant news items.
Read them by running the command 'home-manager news'.
Any clues on what is going wrong? I can’t think of a reason as to why home-manager does not have permission to remove-then-copy the custom-fonts, when it could happily copy the fonts from home.packages.
PS: Initially, the activation script did not have the rm command. Even in that case, the second run had failed because of lack of permission to cp.

Alright. I figured it out.
While executing the activation script, home-manager copied the files with read-only permissions for all, including the user themselves:
>> ls -ld ~/Library/Fonts/HomeManagerExtra/InputMono/InputMonoCondensed
dr-xr-xr-x 16 jayesh staff 512 Jun 10 12:24 /Users/jayesh/Library/Fonts/HomeManagerExtra/InputMono/InputMonoCondensed

This happened only to the custom-fonts installed by the activation script. The fonts installed from home.packages had the correct permissions:
>> ls -ld ~/Library/Fonts/HomeManager/opentype
drwxr-xr-x 100 jayesh staff 3200 Jun 10 12:24 /Users/jayesh/Library/Fonts/HomeManager/opentype
>> ls -ld ~/Library/Fonts/HomeManager/opentype/FiraSans-Bo*
-rw-r--r-- 1 jayesh staff 305832 Jun 10 12:24 /Users/jayesh/Library/Fonts/HomeManager/opentype/FiraSans-Bold.otf
-rw-r--r-- 1 jayesh staff 314492 Jun 10 12:24 /Users/jayesh/Library/Fonts/HomeManager/opentype/FiraSans-BoldItalic.otf
-rw-r--r-- 1 jayesh staff 296368 Jun 10 12:24 /Users/jayesh/Library/Fonts/HomeManager/opentype/FiraSans-Book.otf
-rw-r--r-- 1 jayesh staff 306464 Jun 10 12:24 /Users/jayesh/Library/Fonts/HomeManager/opentype/FiraSans-BookItalic.otf
So I modified the permissions after copying, in the activation script:
home.activation = if pkgs.stdenv.isDarwin then
{
copyExtraFonts = lib.hm.dag.entryAfter ["writeBoundary"] ''
$DRY_RUN_CMD rm -rf $VERBOSE_ARG ~/Library/Fonts/HomeManagerExtra
$DRY_RUN_CMD cp -r $VERBOSE_ARG ${../configs/fonts} ~/Library/Fonts/HomeManagerExtra
$DRY_RUN_CMD find $VERBOSE_ARG ~/Library/Fonts/HomeManagerExtra -type d -exec chmod 744 {} \;
$DRY_RUN_CMD find $VERBOSE_ARG ~/Library/Fonts/HomeManagerExtra -type f -exec chmod 644 {} \;
'';
} else { };
Now the permissions are set correctly.
>> ls -ld ~/Library/Fonts/HomeManagerExtra
drwxr--r-- 4 jayesh staff 128 Jun 10 12:31 /Users/jayesh/Library/Fonts/HomeManagerExtra
>> ls -ld ~/Library/Fonts/HomeManagerExtra/InputMono/InputMonoCondensed
drwxr--r-- 16 jayesh staff 512 Jun 10 12:31 /Users/jayesh/Library/Fonts/HomeManagerExtra/InputMono/InputMonoCondensed
>> ls -l ~/Library/Fonts/HomeManagerExtra/InputMono/InputMonoCondensed/InputMonoCondensed-B*.ttf
-rw-r--r-- 1 jayesh staff 136664 Jun 10 12:31 /Users/jayesh/Library/Fonts/HomeManagerExtra/InputMono/InputMonoCondensed/InputMonoCondensed-Black.ttf
-rw-r--r-- 1 jayesh staff 139304 Jun 10 12:31 /Users/jayesh/Library/Fonts/HomeManagerExtra/InputMono/InputMonoCondensed/InputMonoCondensed-BlackItalic.ttf
-rw-r--r-- 1 jayesh staff 109516 Jun 10 12:31 /Users/jayesh/Library/Fonts/HomeManagerExtra/InputMono/InputMonoCondensed/InputMonoCondensed-Bold.ttf
-rw-r--r-- 1 jayesh staff 112248 Jun 10 12:31 /Users/jayesh/Library/Fonts/HomeManagerExtra/InputMono/InputMonoCondensed/InputMonoCondensed-BoldItalic.ttf
Reruns of home-manager switch work as expected.
