What were you trying to do that didn't work?
Apply updated boot options in /etc/default/grub with grub2-mkconfig
Please provide the package NVR for which bug is seen:
grub2-tools-2.06-70.el9_3.2.x86_64
How reproducible:
Every time grub2-mkconfig --update-bls-cmdline is run and there are escapes (i.e. backslashes) in GRUB_CMDLINE_LINUX
Steps to reproduce
1. Update the GRUB_CMDLINE_LINUX in /etc/default/grub with some directive which has special characters (particularly "&", since grub cannot read it) which are escaped. For example:
cat /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=rhel/root debug boot=UUID=XXXX ds=hostname-net\;s=https://someurl:port/url\&foo"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true
2. Run "grub2-mkconfig --update-bls-cmdline -o /boot/grub2/grub.cfg"
3. The boot options in grub.cfg are escaped as expected, but the ones in the /boot/loader/entries files are not. For example:
$ less /boot/loader/entries/XXXX-5.14.0-284.30.1.el9_2.x86_64.conf
...
options root=/dev/mapper/rhel-root ro rd.lvm.lv=rhel/root boot=UUID=XXXX ds=hostname-net;s=https://someurl:port/url&foo
$ less /boot/grub2/grub.cfg
...
the kernelopts variable in the grubenv file and the fallback kernelopts variable.
if [ -z "${kernelopts}" ]; then
set kernelopts="root=/dev/mapper/rhel-root ro rd.lvm.lv=rhel/root boot=UUID=XXXX ds=hostname-net\;s=https://someurl:port/url\&foo"
fi
Expected results
The boot options placed in /boot/loader/entries files should include escapes like the ones in grub.cfg.
Actual results
Escapes are lost when options are copied into blscfg entries.
