A voice from Pico user, whose interest is in a shirt-pocket operating system capable of dial-in and plugging into a network, asks that as far as Pico is concerned what difference would it make? As far as I have discovered, all bytes on the Pico disk are permanent except for the ppp configuration. Although Pico will mount msdos and ext2fs floppy disks, it constantly complains when reading dos disks that it can't write to them because they are write protected. (!) If I mount an ext2 disk Pico page-faults as soon as I do an ls... So, to clarify my question, assuming funtionality to be first consideration and speed/memory secondary, and assuming also that the mount problem would be fixed, within the size limitations of a floppy, wouldn't this limitation of your feature have no big negative effect for Pico? I certainly appreciate all the work that has gone into the Pico project, and only dip into it from time-to-time. And I am very glad to see that things are moving forward. -Bill Cassady To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-small" in the body of the message
