Hello,

tail ask me to send bugreport to your email address, and I am doing it.

When using Parallels 11 OS X with Vagrant and Ubuntu guest, got this error. `tails` utility can't detect `prl_fs` filesystem.

tail: unrecognized file system type 0x7c7c6673 for 'file.log'. please report this to address@hidden. reverting to polling

Hello Pádraig,

Heh 0x7C7C6673 is ||fs in ASCII. I like it :)

Me too :)

Could you install inotify-tools and use inotifywait to see if inotify is 
supported on prl_fs?
That will let us tag it appropriately.

I did it. Mixed picture:
1. Run `inotifywait -e modify /vagrant/out/1.txt` and run `echo 123 >> 
/vagrant/out/1.txt` both from inside VM (in different shell sessions).
Setting up watches.
Watches established.
/vagrant/out/1.txt MODIFY
2. Run `inotifywait -e modify /vagrant/out/1.txt` from inside VM and run `echo 123 
>> /vagrant/out/1.txt` from outside VM.
Setting up watches.
Watches established.
(just waiting, nothing fired)

I use native Parallels Tools installed inside VM.

FS mounted as (it is mounted automatically by Vagrant and Parallels):
vagrant on /vagrant type prl_fs (rw,uid=1000,gid=1000)

Excellent.
I'll push the attached later.

thanks,
Pádraig
