[Vserver] copy-on-write after unification?
Hello,I have trouble when unifying vservers and then trying to personalize unified filesExample:Unification of vservers vtest6 and vtest5 (vtest5 as the reference server for vtest6)I did: Copy from vtest5 to vtest6:# vserver vtest6 build -m skeleton --hostname vtest6 --interface eth0:127.0.0.1 --interface t1=eth0:10.200.0.6 --context 6 # cp -pr vtest5/* vtest6/ Reference server declaration as described in http://linux-vserver.org/alpha+util-vserver :# mkdir -p /etc/vservers/vtest5/apps/vunify # mkdir -p /etc/vservers/vtest6/apps/vunify # ln -s /etc/vservers/vtest6 /etc/vservers/vtest5/apps/vunify/refserver.00Unification:# /usr/lib/util-vserver/vunify vtest6It seems to work fine as files in both directories have same inode But trying to modify unified files is not transparent and I have to manually copy, delete and rename the copy:vserver:/# vserver vtest5 entermesg: /dev/pts/1: Operation not permittedvtest5:/# ls -i /tests 508984 testfile 508985 testfile2vtest5:/# exitlogoutvserver:/# vserver vtest6 entermesg: /dev/pts/1: Operation not permittedvtest6:/# ls -i /tests508984 testfile 508985 testfile2vtest6:/# cat /tests/testfile bash: /tests/testfile: Permission deniedvtest6:/#Is there a way to make it automatic?And would you have any info about that mesg: /dev/pts/1: Operation not permitted occuring each time I enter a vserver?
