[Fingerforce-devel] Bug#1122235: postinst script makes installation hang for several minutes

[Johannes Schauer Marin Rodrigues]

Source: libfprint
Version: 1:1.94.9-1
Severity: normal

Hi,

I just installed a package unrelated to libfprint but then my
installation got stuck for more than five minutes at trying to set up
libfprint. Looking at htop I saw the postinst script being busy calling
"udevadm trigger". This operation did not cause CPU nor I/O load on my
system but it still took several minutes to go through the list of
devices.

Could this be sped up somehow? Could udevadm not be called in parallel
instead of in series?

Or could at the very least not something be printed on stderr like "This
can take a very long time"?

Thanks!

cheers, josch
