But in icecat there is tow issues, one is related with the /etc/localtime that expect a symlink but also there is another one related with firefox sandbox, you can see here that `/usr` and `/nix` was added to a whitelist, those paths is where they expect have the zoneinfo files and `/gnu` is not in that whitelist (I already reported to firefox), and disabling `MOZ_DISABLE_CONTENT_SANDBOX=1` it and with the symlink the timezone works again. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQFJBAEBCAAzFiEEvYwofabWO6y953lVmAk6gHJUa/MFAmWxKI8VHGRpc3RvcGlj b0ByaXNldXAubmV0AAoJEJgJOoByVGvzt64H/itK+zRRGsgA3o+5kr211Fa/OI84 GLdNKTAYgu3YQSZsUH58hhg0LA2uiX1vrbuMES5vQrnHJSrbavN8Ljk92BNLKs6W y7s7mVbpicILys6AI5Hv15IspHRJ58qOLEqFlkTxlDNhsbbqUyyOzZtkdJEym6+X uPyipLr4xx7W6GuQ/HJv0kRDSbvrW6klByBQnBgLh0je/YG31eRk04D+1WaYaII/ gysDeEwmdkEyDbHxmt91pblELcGiqp8jI3OS/VzmvH4wy9O5IhcrGMUE0Bj1pPFU ZDarKyeF5W5BWvG4vK2PA5LsNQGrVxUGvyqURjCkgyg44x+MSiKeR0UrN/g= =cJuv -----END PGP SIGNATURE----- --=-=-=--

Icecat in other hand has an additional bug related with icu[2][3] and folder policy where `/gnu` is not allowed so in order to make it work is necessary disable sandbox `MOZ_DISABLE_CONTENT_SANDBOX=1 icecat` or set manually TZ env `TZ=$(cat /etc/timezone) icecat`, btw I have `privacy.resistFingerprinting` false. The weird thing is that in almost all of those reported the error is the opposite where having a realpath solves it but in guix it is the problem, perhaps it could be because these apps have updated their code to make it work with `icu` v72 and guix has v71. Steps to reproduce it: - guix pull && guix package -u - Install last icecat or ungoogled-chromium version - Verify that you don't have $TZ set, unset it. - If it's Icecat open `about:config` and set `privacy.resistFingerprinting` to false - Open https://webbrowsertools.com/timezone/ in the browser - Check the timezone - sudo rm -r /etc/localtime && sudo ln -s $TZDIR/$(cat /etc/timezone) /etc/localtime - Open chromium or `MOZ_DISABLE_CONTENT_SANDBOX=1 icecat` - Visit https://webbrowsertools.com/timezone/ again, check the timezone.
