A udev rule installed by media-sound/alsa-utils-1.2.13-r2 (possibly earlier versions too, though I haven't tested) references /usr/bin/cat, which does not exist on my split-usr system. The rule in question is in /lib/udev/rules.d/90-alsa-restore.rules - here's the context: > LABEL="alsa_hda_analog" > # restore configuration for profile with combined cards (HDA + digital mic) > TEST!="/run/udev/alsa-hda-analog-card", GOTO="alsa_restore_std" > IMPORT{program}="/usr/bin/cat /run/udev/alsa-hda-analog-card" > ENV{ALSA_CARD_HDA_ANALOG}!="", ENV{ALSA_CARD_NUMBER}="$env{ALSA_CARD_HDA_ANALOG}" ----- Portage 3.0.67 (python 3.13.3-final-0, default/linux/amd64/23.0/split-usr, gcc-14, glibc-2.40-r8, 6.6.21-gentoo x86_64)
