Hello Debian,
Kernel 2.4.27-10
With mount isofs filesystem, any mount parameters after
iocharset=,map=,session= are ignored.
Sample:
mount -t isofs -o uid=100,iocharset=koi8-r,gid=100 /dev/cdrom /media/cdrom
gid=100 - was ignored
I look in source and find that problem. I make two patch, simply and full
(what addeded some functionality - ignore wrong mount parameters)
simply patch:
