What could be the deal, when Firefox tries to stop me from unmounting a stick, after I've accessed files on it through Firefox? I worry about my stick security. Thanks.

Likely what it means is that you have an open write path from firefox to the stick that has not been properly closed. I get into a similar state working with u-sd's using mc to edit something I have used mc to cd to, and forget to cd back out of the u-sd before I eject the card to take it to its proper home in a pi clone. Possibly fixed by stopping firefox first? Cheers, Gene Heskett, CET. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Possibly fixed by stopping firefox first? The other thing I try with this is to run something like: $ mount|grep sda2 The "sda2" can be replaced with whatever else is involved. That filters out a hopefully small(er) list to show if something is unusually mounted. Running "mount" alone opens up the whole list. Going that route helped me in chroot a couple days ago. An unbelievable number of /proc, /sys, /dev, and /dev/pts mount points appeared. I only manually mounted them once each. Manually umount'ing each point until none were left fixed whatever trouble that seemed to inflict on apt-get.

I worry > about my stick security. Thanks. It sounds like Firefox has a file open on the stick. To check this, run something like lsof | grep -i offsite where offsite is in the path to the stick. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/

I worry about my > stick security. Thanks. Linux knows what files are open on each file system. If you try to unmount a file system with open files or eject a mounted USB drive with open files, Linux will refuse and your desktop environment will display a suitable error dialog. This is a feature, not a bug. The solution is to close all the files on the file system, and then unmount it. David
