I have the following in /etc/apt/apt.conf: Dpkg::Pre-Invoke {"/bin/mount -o remount,rw /usr";}; Dpkg::Post-Invoke {"/bin/mount -o remount,ro /usr";};
However, in many cases, running aptitude results in the following error: mount: /usr is busy E: Problem executing scripts DPkg::Post-Invoke '/bin/mount -o remount,ro /usr' E: Sub-process returned an error code I can't figure out why aptitude is leaving the partition in a state where it can't be remounted ro, even after a significant amount of time has passed or /bin/sync has been called. Running "fuser -vm /usr" reveals that /usr/lib/iceweasel/firefox-bin is being left open for writing (why???), but even after closing firefox and seeing /usr/lib/iceweasel/firefox-bin disappear from the fuser output, the problem remains the same. How do I work around this issue, or at the very least find out why the filesystem is being held open? -- "Oh, look: rocks!" -- Doctor Who, "Destiny of the Daleks" -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
