Since I am shy, I am posting this here (and not to the LKML).
I am including to patch files: patch-hostfsfix.gzThis one fixes a crash when trying to mount hostfs, an error on how the mount options were passed and fixed the setattr to set the time correctly (touch command works now).
patch-frhost.gzThis is a hack of hostfs. Essentially it adds a new filesystem type to UML, frhost. This filesystem is nearly identical to hostfs except one big difference: It stores and uses file ownership, permissions and mknod data from an external ".meta" file. All files under frhost are created using 0700 mode and owned by the UID of the UML process, however, internally, these files may be owned by the UML users. I guess this is similar to HUMFS (but I couldn't find it before I made my own).
BTW, frhost is limited to run over filesystems that use real i-node numbers. So it will not work over FAT file systems, for example.
PS: I have succesfully tested frhost as root file system and also compiling the linux kernel.

No. hostfs is _at the moment_ unmaintained. There is a rewrite of hostfs(based on the new externfs), but it is nowhere near merging (it's under slowdevelopment since at least an year).
