Implement the AFS feature by which @sys at the end of a pathname component may be substituted for one of a list of values, typically naming the operating system. Up to 16 alternatives may be specified and these are tried in turn until one works. Each network namespace has[*] a separate independent list. Upon creation of a new network namespace, the list of values is initialised[*] to a single OpenAFS-compatible string representing arch type plus "_linux26". For example, on x86_64, the sysname is "amd64_linux26". [*] Or will, once network namespace support is finalised in kAFS. The list may be set by: # for i in foo bar linux-x86_64; do echo $i; done >/proc/fs/afs/sysname for which separate writes to the same fd are amalgamated and applied on close. The LF character may be used as a separator to specify multiple items in the same write() call. The list may be cleared by: # echo >/proc/fs/afs/sysname and read by: # cat /proc/fs/afs/sysname foo bar linux-x86_64 Signed-off-by: David Howells <dhowells@redhat.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
