I occasionally use Cygwin installed to NTFS partitions of USB flash drives for many years now. No problems so far, but the use cases were typically limited to "rescue" purposes (mintty, dd, ddrescue, fdisk, hexedit, smartctl, testdisk, ...). BTW: Also works great from the limited WinPE environment booted from a FAT32 boot partition on same flash drive. > I prefer to put CygWin on an USB flash drive and run it on various > computers without leaving installation traces. Please be aware that there will be traces on all computers because a registry value is set during startup of the root cygwin1.dll. The values appear below one of the following registry keys: HKEY_LOCAL_MACHINE\SOFTWARE\Cygwin\Installations HKEY_CURRENT_USER\SOFTWARE\Cygwin\Installations A list is included in 'cygcheck -s' output. Alternatively try the following commands from Cygwin shell: ls -la /proc/registry??/HKEY_LOCAL_MACHINE/SOFTWARE/Cygwin/Installations ls -la /proc/registry/HKEY_USERS/*/SOFTWARE/Cygwin/Installations Regards, Christian
