[opensuse] Changing cramfs contents
Can someone give me some info on changing the contents of a cramfs file? I have mounted the file using: mount -o loop -o rw file1 tmp but when I try and change/delete a file I get an error stating the filesystem is readonly. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Maybe I'm wrong, but schouldn't your command read: mount -o loop,rw file1 tmp -- MfG, David Mayr =========================== LunaBOX Network Solutions =========================== Haubensteigweg 55 D-87439 Kempten TelNr: 0831-5124808 FaxNr: 0831-5124809 Mobil: 0172-8673184 www.lunabox.de info@lunabox.de ================== -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Same results as what I used. I end up with a mounted filesystem showing: type cramfs (rw,loop=/dev/loop1) but I cannot change anything. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

cramfs is a readonly file system. It is compressed with zlib an meant to be used in ROM. Herbert -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Thanks for everyone's help. I ended up doing the following: created a temp dir as mount point for cramfs filesystem mounted cramfs to mount point using -o loop copied all of the structure to a new dir changed the file that needed changing in the new dir created new cramfs to replace original -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

it's like iso9660 in terms of being readonly, and practically superseded by squashfs. -`J' -- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I did this so I could install 10.2 from a local HD. I'm one of the lucky ones that needs support for the cciss driver in qparted that was borked on the orig install media. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
