pacstrap fails: umount: /mnt/dev: target is busy
I'm having some strange issues with pacstrap.
I'm installing it from Arch running off a stick (full install on the stick, not the install media).
I've mounted partitions and installed some stuff with pacstrap, but now it refuses to cooperate.

Re: pacstrap fails: umount: /mnt/dev: target is busy
Are you running your install in a session authorized through polkit?

It was in "sudo su" shell, not sure if that's polkit. Only those packages caused it, so it must be something specific to them. Not a big deal, I chrooted inside and did it with regular pacman. Just weird...

Yea I was in Xfce, booted from a usb drive, trying to install Arch on hard disk.
And succedded, so this doesn't need to be solved... I'm now just curious what was wrong
It worked for all other packages, just not for those gstreamer plugins - after that, I had to reboot

Log in as root from a virtual terminal [Alt]-[F2...n] tty instead.
Had a similar issue with archiso a while back and that's the only way I ever got it to work.
