I concure that G4U is also good program, and have had some discussions 
with Mr. Feyrer, since there were some issues with the previous maintainers 
of G4L and him. I believe these have been resolved. I found the G4L project 
in a state, and was able to make updates since I had access to linux, but no 
NETBSD experience.

The above is a little outside my experience. I've generally found that g4l 
supports hardware that g4u doesn't, at least with the later linux kernels. I 
have had a couple of users that had hardware that didn't work, and either 
adding modes to the kernel.org  kernels, or waiting till the support was added 
to the kernel. The g4l has many kernels on the iso, so that if the default 
doesn't work, the older ones might. So, not sure if the issues you referred to 
might be people that the default kernel didn't work, or later versions might.

I wish I did have more users communicate. Generally get 8,000 or more 
downloads a month.

The ease of using ftp or external usb devices to backup, and with later 
versions sshfs and cifs with the 0.30 versions. It also has the option of doing 
NTFSCLONE backups of ntfs partitions that are much faster than dd 
backups.

For the most part I see this as an USB 1 verses USB 2 support. Found that 
some P4 still had only USB 1, and about 1MB is the best you could get, with 
a USB 2 supprt it wasn't as fast as have an IDE connection.

The biggest issue with G4L has been the outdated documentation, and I 
have 3 students working on updating the documentation, but they had little 
linux or scripting background, but have gotten use to running the program.
