maco(but not the other way around)06:05
angel_is it possiable the kernel swap the page that mmapped from file??06:18
EruditeHermithello, is it possible to build a 32bit kernel on 64bit karmic?06:22

EruditeHermitAceLan, do you have the script that is mentioned on that page? The link to it is broken07:52
AceLanEruditeHermit: I just fixed the link, please try again07:59
EruditeHermitAceLan, still getting 40408:00
AceLanEruditeHermit: I can download it, maybe your browser need to reload the page :p08:07
EruditeHermitah it works now08:08
EruditeHermitAceLan, does the script make any permanent changes?08:08
EruditeHermitAceLan, can I just rm -rf /var/chroot and nothing else will have changed?08:08
EruditeHermitAceLan, also, the page is a little unclear. Can I run the script and just use the chroot immediately or do I have to perform the steps in the sections below the initial script section08:10
AceLanEruditeHermit: the script will do most of the work describe in the following section below.08:11
AceLanEruditeHermit: The script will modify /etc/fstab, you have to take care of thar file, if you remove the chroot directory08:12
EruditeHermitAceLan, what does it to to fstab?08:13
EruditeHermitAceLan, as a request, if you made the script have an uninstall option, that would be really cool08:15
AceLanEruditeHermit: haha08:16
AceLanEruditeHermit: It will modify the fstab, so that fstab will mount the filesystem that use by the chroot08:18
AceLanEruditeHermit: uninstall is much more difficult than install, I'll think about that, thanks for the suggestion :)08:19
EruditeHermitjust make a copy of fstab as a backup08:19
EruditeHermitremove the /var/chroot/hardy-lpia or whatever08:19
EruditeHermitand then copy the backed up fstab back to /etc/fstab once done08:19
AceLanEruditeHermit: haha, not so easy, what if you have more than one chroot?08:20
EruditeHermitso make it an option to delete each chroot individually08:20
EruditeHermitand make an option to delete all08:21
EruditeHermitthe delete all will replace the fstab08:21
EruditeHermitthe individual chroot delete will just rm -rf /var/chroot/specific-chroot08:21
AceLanEruditeHermit: looks like you're very interesting in this, would you like to write one :)08:22
EruditeHermitAceLan, I am not skilled enough =p08:25
EruditeHermitAceLan, it would be nice if you knew awk/sed etc to edit fstab to remove each relevant entry08:25
EruditeHermitAceLan, I just dislike having cruft left behind on my machine08:25
EruditeHermitone thing I love about most distributions is that they keep track of files08:26
EruditeHermitother OSes get bloated with random stray files everywhere08:27
AceLanEruditeHermit: you have to track the chroot related files by yourself, I don't have to much time to rewrite the script now, but I'll do it once I have time. :p08:29
EruditeHermitAceLan, ok08:34
EruditeHermitAceLan, but you assure me that the only related files are in /var/chroot and /etc/fstab08:34
AceLanEruditeHermit: and /etc/schroot/schroot.conf, /etc/dchroot.conf :p08:35
EruditeHermitAceLan, thanks for your help today08:46
EruditeHermitI may ask you more questions about it later08:46
EruditeHermit=)08:46
EruditeHermitits a cool script08:46
AceLanEruditeHermit: :)09:39
