recent quota tools from Honza are fine, no
modifications are required, vfsv0 (the new quota
format) is required to make linux-vserver quota
useful (with the old format, you get GB sized
quota files ;)

right, quota is modified by linux-vserver quota
patch to allow for more than one quota hash per
filesystem. this requires a way to add/remove those
hashes to/from the filesystem. this is done by the
linux-vserver quota tools cqhadd/cqhrem. disk limits
are another feature, addressed by the cqdlim tool

the 2.6 branch (vs1.9.x) doesn't support vserver
quota atm, just disk limits, and they are handled
by a new tool (vdlimit) which is compareable to
the cqh* tools. in near future per vserver quota
support will be added to vs1.9.x ...

I guess 'recommend' is something like 'depend on'
just not mandatory, well, if so, then this sounds
reasonable to me. anyway here are the dependancies:

 for 2.4/1.2x
   
 disk limits -> quota patch, cq-tools
 vserver quota -> quota patch, cq-tools, quotatools, vrsetup
 secure quota -> quotatools, vrsetup (separate partition)
 
 for 2.6/1.9x

 disk limits -> vdlimit
