Public bug reported:
Title: dracut 110-11: 50-parse-copymods.sh warns about deprecated
'copymods' on every boot
Package: dracut-core 110-11 (dracut, dracut-core, dracut-install,
dracut-network)
Kernel: 7.0.0-29-generic
The compatibility hook
/var/lib/dracut/hooks/cmdline/50-parse-copymods.sh
prints this warning during initramfs on EVERY boot:
"Kernel command line option 'copymods' is deprecated, use
'rd.driver.export' instead."
even when 'copymods' was never passed on the kernel command line.
/proc/cmdline confirms neither 'copymods' nor 'rd.driver.export' is present:
BOOT_IMAGE=/vmlinuz-7.0.0-29-generic root=/dev/mapper/ubuntu--vg-
ubuntu--lv ro quiet splash fbcon=rotate:3 crashkernel=...
Cause: the warn() call is unconditional. The hook only skips when
rd.driver.export is already set (early return). Otherwise it reads
copymods (which may be empty), then always warns and always appends
rd.driver.export. Since copymods is on by default and rd.driver.export
is off by default, the shim legitimately needs to run to preserve
behaviour — but the deprecation warning should only fire when copymods
was actually specified.
Hook contents:
#!/bin/sh
command -v getarg > /dev/null || . /lib/dracut-lib.sh
if getarg rd.driver.export > /dev/null; then
return 0
fi
copymods=$(getarg copymods) || true
warn "Kernel command line option 'copymods' is deprecated, use
'rd.driver.export' instead."
echo "rd.driver.export${copymods:+=$copymods}" >>
/etc/cmdline.d/50-copymods.conf
Suggested fix: guard the warning so it only fires when copymods was
explicitly given, e.g.
[ -n "$copymods" ] && warn "Kernel command line option 'copymods' is
deprecated, use 'rd.driver.export' instead."
