Wasn't meant to be commiserative. I went to report this issue and did a 
search first to see if anyone else has seen it.

- Using setup.exe version 2.677
- We have a local mirror which is updated using rsync (daily)
- The local mirror is accessed as a network share on the Windows 
machines, which is mapped to a drive letter.
- In setup.exe, select 'Install from Local Directory'
- The root directory is: C:\cygwin
- Install for: All users
- Local package directory for us is: M:\apps\cygwin (the network share)
- Select all packages to install (if it's a new installation. For an 
upgrade we take the default selections)
- During the installation, we get pop-ups that say "can't open 
M:\apps\cygwin for reading: Unrecognisable file format". Those pop-ups 
must be dismissed for the installation to finish, and they happen many 
times (52 times for a new, full installation)
- Once setup is complete, Cygwin appears to work OK.
- We've observed this on both fresh new installations as well as with 
upgrades from 1.5
- We've observed this on Win7 64bit and on XP 32bit.

These lines appear throughout setup.log.full and correspond to the popups:
2010/01/27 17:27:12 mbox note: Can't open file://M:\apps\cygwin\Current/ 
for reading: Unrecognisable file format

Hopefully this is enough detail :)
