Re: [webmin-devel] [patch] quota v2 - vsfv0 not supported before 2.4.19 kernels

[Jamie C. <jca...@we...>]

Thanks for the information .. despite all the tricks that the module 
does to support the various quote versions, it looks like I have 
missed some!

However, oddly I can enable quotas with no problems on my Redhat 9 box 
with the 2.4.20 kernel. Any ideas why that might be?
