I am still confused how 400 permission for grub.cfg can work at all. Depending on the upstream grub version, it either cats things to it, or moves a new file to it. In both cases, either permissions reset to 600 or write is not allowed at all. Or one has custom/distro/downstream patched grub that does something different.
Are you inspecting grub.cfg which is stored on non-posix filesystems with restrictive mount umask set? I.e. grub.cfg stored on ESP mounted with fmask=0022,dmask=0022 ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1933826 Title: default file permissions on bootloader configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1933826/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
