20518	kernel modules being rebuilt on each linux system startup => Fixed in SVN	yury_t		"Possibly known issue already.
Happens on 'other' linux system installation, as made from 
VirtualBox-6.1.26-145957-Linux_amd64.run. System is slackware-CURRENT.

The root of the problem seems to be vboxdrv.sh, which is copied to /etc/rc.d/init.d, and sourced from there, and contains this stuff at line 330:
{{{
[ ""$mod_dir"" != ""misc"" ] || return
}}}
...which breaks program's logic. It needs to be: 
{{{
[ ""$mod_dir"" = ""misc"" ] || return
}}}
I made this change in my installation, issue's gone."	defect	closed	other	VirtualBox 6.1.26	fixed			all	Linux
