 One of the most
frustrating things about installing or upgrading programs on certain
operating systems is the constant need to have to reboot. This is
especially true with drivers or system files. Why is it that linux can be upgraded without rebooting? Read on to find out.
It
all comes down to how linux and the file system handles files. When
linux runs an executable it loads the whole file into memory and
accesses it from there. This means that there is no connection to the
physical file on the disk drive. When the program is closed and all
connections to the file are cut the file is deleted from memory.
